But what better food to enjoy on a day like this? Pies are circular and delicious, and that's good enough for us. It's good enough for our foodie friends too, as many of them have agreed to let us share their piedeas for breakfast, lunch, dinner and dessert pies.

So whip out that apron and start baking up a bevy of pies for Pi Day. Or, you know, we guess you could go do math or something.

Breakfast - Maple Oat Breakfast Pie

Pie for breakfast? Why not? Start the day off with a hearty Maple Oat Breakfast Pie. It's made with barley flour, maple sugar and rolled oats, but don't be fooled — Nicole Pearce of Arctic Garden Studio insists that this breakfast treat is great any time of day. Get the whole recipe here.

Liren Baker, aka The Kitchen Confidante, developed her recipe for Day-After Turkey Shepherd's Pie when she found herself with an abundance of leftover turkey from Thanksgiving. But a meal like this is too special to be an afterthought, so make it for tonight's Pi Day dinner. Learn Liren's recipe here.

Dessert - Irish Banana Cream Pie

Cap your day off with the ultimate Pi Day dessert: an Irish Banana Cream Pie invented by Aimee Shugarman of Shugary Sweets. It's perfect for three reasons: first off, St. Patrick's Day is right around the corner; second, National Banana Cream Pie Day was less than two weeks ago on March 2; and third, it's pie.
